I enjoyed every moment working with James. He's a great engineer and enjoys sharing his experience and expertise. Bouncing ideas with him was always fruitful, his code reviews thorough, and he was instrumental in helping News release their apps on time. I'd recommend him in the blink of an eye and hope to work with him again the future.

The ‘7 day’ The Times iPad app is an extremely well loved app, with over 200k MAUs across three variants. I headed a far ranging revamp from managing dependancies, visual updates, many delicate internal changes to what is a 5 year old app. Also, a POC for a ‘Single Web View’, a much faster and simpler architecting of the app. New files were in Swift. I was also seconded to the new iPhone (a pure Swift project) app for two months, to speed them up. I implemented a bunch of features, squashed bugs and refactored some un-performant aspects of the app. We met the deadline of being ready when the new website was complete. I continued to support the team whilst back on the ‘7 day’ iPad app.

Founding member in an incredible team. Written entirely in Swift and utilising many aspects of what makes this new language so interesting. I’ve specifically enjoyed just how much the language can define itself and how you can utilise this to make it even more functional, defining operators and approaching something that looks like Haskell!

I created an iOS SDK for a new platform developed by SmartFocus to allow proximity/mobile/personalised marketing messages be sent to consumers through an integrated app. Including location services (geofences), iBeacons and the creation of a complex rules engine to process delivering messages on a variety of inputs. We achieved 75%+ test coverage with over 600 unit and integration tests.

Working on the ‘Betfair Exchange’ app, addressing many visual changes and updates, as the app iwas prepared for iOS8 and beyond. I have since bolstered my use of Kiwi from seeing it help implement over 3000 tests! Betfair’s extensive use of Cucumber based “Frank” tests have made me appreciate just how powerful a sound BDD approach can benefit a project that does not compromise on quality.

Part of the Total Technology programme, I headed the mobile interpretation of an existing crime documenting desktop web app. It takes over a thousand fields to create a ‘CRIS’ report. The app provided a Crime Ref to a victim, at the scene of crime, allowing them to immediately claim on insurance for missing items.

I was brought in to create a top quality iOS app based around learning to drive. I have never been so pleased with my code, the outcome of the project and the fun I have had doing it. My time at red ant has not felt like work! After completing v1 it was decided to improve the app with an extensive visual redesign, I was invited back for this and completed v2 in time and on budget just like v1. The app is now on the store!

Worked on a Cocoa project for external hardware, then project managed for the windows version. Freelancing the work out for the windows portion gave me the strange but enlightening position of being both client and freelancer.
